STEAM-TRAP.

SPECIFICATION formingpart of Letters Patent No. 226,951, dated April 27, 1880.

I Application filed January 28, 1880.

To all whom it may concern Be it known that I, HUGH 0. Aims, ofNew Orleans, parish of Orleans, and State of Louisiana, have invented a new and useful Improvement in Steam-Traps, of which the following is a specification.

'The invention consists in combining with a vibratory arm carrying a water-receiver a side-apertured hollow trunnion, a dischargepipe, a jacketed standard, and an outlet-pipe, as hereinafter described.

In the accompanying drawings, Figure 1 is a sectional plan view of my improved trap in the position for discharge of water; and Fig. 2 is a vertical section 011 line 0050 of Fig. l, the apparatus being in position for receiving water.

Similar letters of reference indicate correspondin g parts.

The tube or hollow arm his supported by its hollow trunnions b c in fixed standards a a. At one end of arm h is attached the receiver A, that is preferably a hollow sphere, and at the other end of arm h is a weight, B, which is sufficiently heavy to overbalanoe the receiver A and retain the latter in the position shown in Fig.2 until it is filled with water to the extent required.

The steam-pipe to be drained is connected to the trunnion b at the standard a. The trunnion c is closed at the outer end and is provided with side openings, and the trunnion e is formed with a jacket around the trunnion c, which has openings 1, to coincide with the openings in the trunnion when the receiver falls, and also communicates by suitable openings with the discharge-pipe m. These devices constitute a valve that is opened and closed by the vibration of the arm h.

From the back of trunnion c a pipe, (1, passes through the arm it into the receiver A, and terminates near the bottom thereof.

In operation the water enters through the trunnion b, and passes, by pipe h, to the receiver A, as indicated by the arrows, until sufficient water has accumulated to overbalauce the weight B, and the receiver falls and opens communication with pipe at. The water then goes out by pipe (1, trunnion c, and pipe m, and is succeeded in the receiver A by steam until the weight B again restores the receiver to its raised position.

The vibration of the arm h is limited by a stop, 1, that is fixed beneath the arm, and the trunnions will be fitted with steam-tight 'iackings.

The weight B is preferably a hollow sphere containing shot.

This construction furnishes a steam-trap which will act to discharge more or less frequently, as required, and remain in constant operation, if necessary.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patcut- In steam-traps, the combination, with the vibrating arm h, carrying the water-receiver, of the hollow trunnion 0, having side apertures, the discharge-pipe d, jacketed standards a a, and pipe m, substantially as shown and described.
